Household light switch wiring method introduction light switch wiring precautions

First, the type of light switch

The light switch is divided into a single control switch, a dual control switch and a three control switch. In the household light switch, if you are auto-operating during the installation, the first thing you need to understand is which switch is the light switch you have connected.

Second, single control light switch wiring method:

1. Pass the zero wire directly through the lamp cap and place the wire on the center of the switch.

2. Connect the two sides of the light switch with other models.

3. At the time of the exit, one is connected to the center point of 220v, and the other is connected to the switch.

4. Finally check to see if the switch can work normally after power-on.

Third, dual control light switch wiring method:

We first determine the center point of the dual control switch, and the symmetrical point is called the left and right.

1. Connect the two left and right switches in parallel with each other. One switch is connected to the live wire, and one switch is directly connected to the control line.

2. Connect the center point directly with one wire and the electric light to the other end. Check whether the live wire and the neutral wire are correctly connected between the switches.

3. It is better to check whether the circuit is correct, and then check if the lamp can achieve dual control.

4, this control method is a safety hazard, easy to trip, and a little trip, the entire line will have problems.

Four or three control light switch wiring method:

When installing the three-control light switch, everyone needs to pay attention to figure out how it works. The three switches in the figure are ordinary switches, only in different positions, and the positions of the live and neutral lines are also clear. In fact, the control is actually only the two switches 1, 3, and the middle 2 is only a midway switch, by determining the state of 1 and 3 to determine the way they operate. Please refer to the following figure for the specific wiring method:

Five, matters needing attention

Safety is very important when wiring the light switch, so first of all, we must be powered off when wiring. It should be noted that the installation of the luminaire and the switch panel must be done after the wall painting or wallpapering work is completed, and then the installation of the luminaire and the installation of the switch socket panel. It is important to organize and clean, and you must not mess with the wires. After reading this article, I hope to be able to help you. If you still have questions, be sure to make sure that you don't operate blindly. Safety is the most important thing.
